Two long straight parallel wires are 12 cm apart. Wire A carries 2.5 A current. Wire B's current is 3.7 A in t?Two long straight parallel wires are 12 cm apart. Wire A carries 2.5 A current. Wire B's current is 3.7 A in the same direction.1) Determine the magnetic field magnitude due to wire A at the position of wire BB = ? T2) Determine the magnetic field due to wire B at the position of wire A.B = ? T3) Are these two magnetic fields equal and opposite? Why or why not?4) Determine the force on wire A due to wire B, and the force on wire B due to wire A.
(1) wire-A B = (uo)(I) / (2pi * r) B = (1.26E-6)(2.5) / (2pi * 0.12) B = 4.17E-6
